Dr. Sankar Navaneethan discusses an analysis that suggests losing weight could preserve kidney function in obese people with kidney disease. Navaneethan and his collegues analyzed 13 separate studies that assessed the impact of diet, exercise, and surgical procedures on kidney functions. The findings imply that weight reduction may prevent the progression of kidney disease, but he notes that more research is needed.
